The next phase of setting up the GSA 28 based trim control system is to verify and
set the proper functionality of the trim system in the air. Refer to Section 1.7.4.3.1
for general autopilot use and functionality.
WARNING: This stage of the flight test involves allowing the GSA 28 auto-
pilot servos to manipulate the flight control surfaces of the aircraft. Extreme
caution should be used during this phase of the flight test. The pilot should
always have easy access to the autopilot disconnect button to disconnect
the autopilot and take control of the aircraft at anytime.
At a minimum, please follow the following safety guidelines before the initial
autopilot engagement:
• Quick access to autopilot disconnect
• Safe altitude above and away from all terrain and obstacles
• No air traffic in the area
• Safe airspeed below maneuvering speed (VA)
1) Use the Setup page in normal mode to adjust the trim motor speed to get
the desired manual electric trim response.
a) Press the knob on the G5 to access the menu.
b) Select Setup from the menu.
c) Note the low and high airspeed threshold settings on this page.
d) Select the Autopilot Roll Servo, Autopilot Pitch Servo, or Yaw Damper
pages as applicable.
e) Adjust the trim motor speeds at the two airspeed thresholds to get a
desirable trim response.
i) Trim aircraft using manual electric trim inputs
ii) Trim response should not be overly slow
iii) Trim response should not be overly fast
